Test Level
Portable and mobile RF communications equipment should be used
no closer to any part of the N
recommended separation distance calculated from the equation
appropriate for the frequency of the transmitter.
Note: Field strengths from fixed transmitters, such as base
stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast, and TV
broadcast cannot be predicted theoretically with survey
accuracy. To assess the electromagnetic environment due to
fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in
which the N-600x is used exceeds the applicable RF compliance
level above, the N-600x should be observed to verify normal
operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating
the N-600x.
Note: These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.
Interference may occur in the vicinity of equipment marked with the
